The 4 3/10 tons of fertilizer will the farmer have left for his other crops.
According to the given question.
Quantity of total fertilizer the farmer have = 13 2/5tons
And, the quantity of fertilizer which is needed by farmer = 9 1/10tons
Since, the quantities are given in mixed fraction.
So, the above quantities can be written as
13 2/5 = 67/5
And, 9 1/10 = 91/10
Therefore,
The quantity of fertilizer will left for the other crops of farmer
= 67/5 – 91/10
= (2(67) – 91)/10
= 134 – 91/10
= 43/10
= 4 3/10tons
Hence, the 4 3/10 tons of fertilizer will the farmer have left for his other crops.
